APPARATUS FOR SINGEING FABRICS.

Application filed. February 18, 1920.

To all whom it may concern.-

Be it known that I, HAR LD TVHITAKER, a subject of the King of GreatBritain, and resident of Hopewell House, Lightcliffe, near Halifax, inthe county of York, England, have invented a certain new and usefulImprovement in Apparatus for Singeing Fabrics,'of which the followingdescription, together with the accompanying sheet of drawings, is aspecification.

It relates to apparatus for use in the singeing of fabrics by theemployment of flames of gas, and consists in so constructing the fabricguiding-devices and arranging same relatively to the positions of thegas flames that the singeing process is carried out by the fabricbein'gpresented to the flame under such conditions as not to distort theflame, but to allow same to assume its natural shape and afford perfectaccess for the atmosphere to support combustion of the fibers that areburnt by the flame.

In the accompanying sheets of drawings which are illustrative of myinvention Figure l is a sectional end elevation of apparatus constructedin accordance with my invention.

Fig. 2 is a plan of the parts shown by Fig. l.

Figs. 3 and i are sectional elevation and plan drawn to an enlargedscale of a certain part hereinafter explained.

Fig. 5 is a sectional elevation illustrative of a modification orextension of the use of my devices, the framework being omitted for thesake of clearness.

To attain the object of my invention, the fabric guiding devices 2 arehollow as her tofore so that the cavities a extending lengthwise saidguiding devices may contain water for cooling purposes such water beingsupplied thereto through the flexible pipes Z) and discharged by similarpipes at the other end thereof. According to my invention the edges 0 ofthe guiding devices 2 over which the fabrics 3 have to take, are reducedto such proportions and are slightly concaved on their side faces (orare made as thin as possible) so that without being too thin forefliciently guiding said fabrics 8 (that is without cutting or damagingsame) their said formation will enable several of said guiding devices 2to be made use of in connection with one and the same flame 4 withoutdistorting the said flame.

Specification of Letters Patent.

Patented Aug. 2 1-, 192-0.

Serial No. 359,705.

The drawings show five of said guiding devices which are arranged toapproach the flame 4: in the respective positions shown, two guidingdevices on each side of the flame and symmetrically arranged in relationthereto, and a guide device arranged to approach the tip of the flame.The guiding devices 2 may be moved toward or from the flame i in orderthat their guiding edges 0 may be adjusted closer to or farther fromsaid flame 4 as occasion may require.

The adjusting devices for each extremity of each of the guides 2 mayconsist of a screw 5 (see Fig. 2) which takes through a bracket 6 uponwhich the sliding bracket 7 is mounted this is made possible by theouter ends of said guide 2 being received by said bracket 7. Therotating of the screws 5 will cause the brackets 7 and the guide toadvance toward or to recede from the flame 4 according to the directionin which said screw 5 is rotated.

On account of the edges 0 being of the formation described, as thefabrics 3 pass over same, the fibers 9 extending from said fabrics arecaused to so radiate (somewhat as shown by Fig. 3 in the drawings) thatthey are projected into the flame 4 to the exact extent desired in ordertobe thereby entirely removed without the surface of the fabrics 3 beingin any way damaged by the actions of said flame 4.

By the guiding devices 2 being of the formation illustrated they mayoccupy such positions relatively with each other, that the fabrics 3passing over same and over the several guiding rollers 8, have betweeneach of their fOlds a comparatively large open space as shown at dcZ byFig. 1 thus the circulation of air in order to support oom- ,bustion aswell as to assist in the removing of the dust or refuse resulting fromthe burnt fibers is freely permitted. Whereas should the guiding edges 0be of circular form or such shape as to present a considerable broadsurface toward the flame even should said flame not be distorted therebyyet I find that the consumption of the fibers by said flame is preventedby reason of the inability of air to flow to that part to supportcombustion.

As is before stated the series of guiding devices 2 may be arranged asshown by Fig. 1 around or in proximity to the entire outer surfaces ofthe flame t or only such portion thereof as may be found advantageouswhile A further than this the fabrics 3 may be taken 7 the opposite sideof the fabric thereto so and the same gas flame 4.

that'the other side of said fabrics will pass over two of said guidingsurfaces thus both sides of the fabrics will be singed by one Thecarrying of the fabrics through the apparatus described is effected bythe rotary rollers 8 certain or all ofwhich may be rotated by anysuitable belt or other driving devices, while when passing beyond saidrollers 8 said fabrics may be received by cutting. or folding mechanism9 as shown by Fig. 5 which comprises a member having spaced walls, themember being adapted to swing back and forth about a pivot, the clothpassing between the spaced walls and being folded and piledin laps oneon top of the other.

, Such being the nature and'object of my said invention, what I claim isI 1. A device for singeing fabrics comprising a burner, a series offixed guides having thin wedge-like edges grouped about the spaceoccupied by a flame projecting from the burner, a series of guidingrollers arranged to cooperate with some of the fixed guides inpresenting one side of the fabric to portions of the flame, and anotherseries of guiding rollers arranged to cooperate with the other fixedguides in presenting the opposite'side of the fabric to other portionsof the same flame so that both sides are singed during a single pass ofthe fabric over the flame. I

2. A device for singeing fabrics comprising a burner and a series ofguiding devices havino'thin wedge-like edges across which the fabricmaybe passed, said edges being grouped about the space occupied by aflame projecting from the burner and arranged to conform to the normalshape of the flame Without distorting the latter.

3. A device for singeing fabrics comprising a gas burner, a pluralityofguiding devices having their wedge-like portions. over the edges ofwhich the fabric may be passed arranged to present the fabric in closeproxtion.

imity to the flame of the gas burner, said wedge-like portions havingconcaved faces, pairs of spaced rollers arranged inrelation to certainof said. guiding devices'so that a web of fabric may be alternatelywound over said guiding devices and a pair of spaced rollers therebyaffording a space of considerableextent between the portions of thefabric. V

4. A device for singeing fabrics, comprising a burner, a series ofguiding devices ar ranged to present a fabric passed thereabout tothe'flame of the burner, said guiding devices comprising 7 thick hollowportions through which a cooling'substance may circulate and thinwedge-like guide edges around which the fabric may be passed.

5. A device for singeing fabrics, comprising a burner, a seriesofguiding devices arranged-to present a fabric passed thereabout to theflame of the burner, said guiding devices comprising thick hollowportions through which a cooling substance may circulate' and thinwedge-like guide edges around which the fabric may be passed, and tubesfor supplying fluid to said hollow por- 6. A device for singeingfabrics, comprising a burner, a series of guid ng devices arranged topresent a fabric passed thereabout to the flame of the burner, saidguiding devices comprising thick hollow portions through which a coolingsubstance may circulate and thin wedge-like guide edges around which thefabric may be passed, and means for folding the cloth whensinged.

- 7. A device for singeing'fabrics, comprising a burner, a series ofguiding devices arranged symmetrically about the flame of said burnerand in position to present a fabric wound about the guiding devices inclose proximity to -said flame.

8. A device for singeing fabrics, comprising a burneija series ofguiding devices arranged about. the of said burner and in position topresent a fabric wound about the guiding devices in close proximity tosaid flame, the guide devices being provided with thin wedge-likeportions having concave faces over which thefabric is lapped, whereby awide space is presented between each pair of approximate guide devices.
